To all whom it maz concern."

Be it known that I, Aoonrii G. SOIST- mizvlv, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia" and- State of Pennsylvania, have invented a new and useful l'lorn of which the following is a specification.

My invention relates to improvements in horns.

lily invention especially relates to herns used for talking machines. and comprises improved means for reinforcing the end of the horn.

My invention comprises inner and outer reinforcing tapered sleeves and means for securing -or locking said sleeves as herein after claimed.

Referring to the drawings :-l igure 1 is an elevation of the horn containing my improved reinforcii'ig sleeve. Fig. 2 is longi-- 'tudinal section of the small end of the horn on anenlarged scale. Fig. 3 is a section of he inner sleeve member. Fig. is a section of the outer sleeve member.

Similar numerals refer to similar. parts throughout the several views.

My invention .is especiallw adapted for horns constructed of wood, fiber or similar material. but need not necessarily be confined to horns of that construction.

Referring to Fig. 2 the outer sleeve member 6 is tapered and provided with an inwardly curved or turned in end The member 7 is provided with an inwardly curved or turned in portion 9 as shown in Fig. 3. The tapered outer sleeve member 6 is forced upon the small end of the horn as ta 7 as it willgo. in the direction of the arrow 11. in Fig.2: while the inner sleeve'member T is forced into the small end of the horn as tar as it will go. in the direction of the arrow 12, in Fig. 2. outer member 6 can now only move in the direction reverse to the arrow. while mem ber T can only move in direction reverse to arrow 12. l f'the inner turned in portion or lip S of member 6 is bent down over the turned in portion or lip 9. of member 7. as shown at 10 in Fig. 2, it will be evident that movement of the member 6 in the direction of the arrow 11 will be prevented by the engagement between the lip 8 and the lip It will be seen that the 9 of said members 6 and 7 respectively, while similarly movement in the direction reverse to arrow .2 of member 7 is also prevented. Therefore said members 6 and 7 are absolutely locked against movement in either direction and cannot be disengaged from the small end of the horn. This construction is espeei -lly desirable where a stud is used on the sleeve member 6 for engagement with the talking n'iacliine. as i engagement has heretofore preuiousl cat sed the disengagement or pulling oil of the sleeve member 6.

What 1 claim is:

l. in combination with a horn. a tapered sleeve surroumlingthe tapered end thereof. and a tapered sleeve tilting within said end. the outer sleeve having a lip turned around the edge of and projecting into the inner sleeve to lock the same therewith.

Z. The combination ot' a horn, a tapered sleeve surrounding the tapered end there-:rl', and a-tapered sleevelitting within said tapered end; the outer sleeve being turned in around the edge of the'horn and the edge oi the inner sleeve.

In combination with a horn. a tapered sleeve surrounding the tapered end thereof. and a tapered sleeve fitting within said laturned lips at the small end thereof. the lip of the outer sleeve being spun around that o1 the inner sleeve after being assembled.

+2. Incombii'iation with a horn. a tapered sleeve lilting over the tapered end of the horn, a tapered sleeve fitting within said tapered end. said sleeves having turned-in portions. one locking with the other, substantially-as described.

In combination with a horn of fibrous material. a tapered sleeve surrounding the tapered end of the horn and a tapered slc vc fitting within said tapered end having a lip or ridge around its smaller margim-the lapered sleeve surroumling.the horn having an inwardly curved lip at its smaller end projecting into the tapered sleeve within the horn and engaging ,with the lip thereof.
